DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 731,568, dated June 23, 1903.-

Application filed November 24, 1902. $erial No. 132,642.

' T aZZ-tvhom it may concern.-

draft-equalizers Be it known that I, HENRYJ. Hnrnnaa citizen of the United States, residing at Templeton, in the county of Carroll and State of Iowa, have invented a new and useful Draft-Equalizer, of which the following is a specification.

This invention relates more particularly to for use in connection with agricultural implements, especially plows, one of the objects being to provide a structure to which four horses may be hitched, so that one will be in the furrow, while the remainder will travel on unplowed ground. It will be understood, however, that a greater or lesser number of draft-animals may be employed.

Another object is to' employ a combination of simple elements to obtainthe desired ends and to construct the same, so that the evener can be readily attached to clevises of different sizes.

The preferred form of construction is shown 1 in the accompanying drawings, wherein- Figure 1 is atop plan view of the equalizer. Fig. 2 is a detail perspective view of the bracket-frame, and Fig. 3 is a detail sectional view through one end of "the draft-bar.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

A draft-bar 10 is employed that may be of any desired or well-known construction and 11, carrying the usual swingletrees 12, thereby making connections for four horses. A body-piece 13 isralso employed, said piece being, preferably, an A-shaped bracket-frame comprising converging side arms 14, connected intermediate their ends by a cross-bar 15.

The free terminals of one of the arms 14. is provided with an offset outstanding ear 16, having atransversely-disposed slot 17, while the correspondingend of the other arm is pro- 1 videdwithalug18, havinga bolt-receiving opening 19 therethrough. Through the open- 1 :ing 19 and theslot 17 are passed fasteningbolts 20, by means of t which the bracketframe can be attached to the clevis, (shown at 21in Fig. 1.) This clevis may be of any well-known construction, and as the fastening-bolts are relatively movable, because one of them passesthrough the slot 17, it will be evident that said bolts may be adjusted to suit the positions of the openings in the clevis. A hammer-strap 22 can also be employed, if desired, one end being fastened by the bolt 20, the other end being attached to the bracketframe.

A stirrup 23 is secured to one end of the draft-bar 10 by means of bolts 24, being located against the rear face of said bar and embracing the clip 25, employed in connecting the whiffletree to the bar. This stirrup is connected by means ofa set of links 26 to the apex of the frame 13, said links being secured by pivots, as 27. Another set of links 28 is employed for connecting the lug 18 with the intermediate portion of the draft-bar, a pivot 29 serving to fasten the links to said lug. The setsof links are thus disposed in angular relation with respect to themselves and the line ofdraft, the pivot 27 being arranged in advance of the pivot 29 of the links 28. By this arrangement the draft-bar 10 is fastened to a plow-beam with one end nearer the line of draft than the other, so that one horse will travel in the furrow previously made by the plow, while the others will be on unp'lowed ground. At the same time no undue side draft is created. The structure is extremely simple, being made up of a few elements that will not easily break or become deranged.

Furthermore, it can be applied to almost any clevis now in general use because of the adjustability of the fastening bolts for the bracket-frame.

From the foregoing it is thought that the construction,operation,and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, is-

1. In a draft-equalizer, the combination with a single rigid draft-bar, of whiffletrees connected thereto, a body-piece, means for securing the body-piece against pivotal movement,and linkspivotallyconnectingthe bodypiece and the draft-bar and holding said bar against horizontal swinging movement.

2. In a draft-equalizer, the combination with a single rigid draft-bar, of whiffletrees connected thereto, a body-piece arranged in a rear of the draft-bar, means for securing the body-piece against pivotal movement, and links'pivotally connecting the body-piece and different portions of the draft-bar, said links being disposed in angular relation and holding the draft-bar against horizontal swinging movement.

3. In a draft-equalizer, the combination with a single rigid draft-bar, of whiftletrees connected thereto, a body-piece, means for securing the body-piece against pivotal movement,andlinks pivotally connecting the bodypiece and different portions of the draft-bar to hold said bar against horizontal swinging movement, said links being disposed in angnlar relation with respect to themselves and the line of draft and also constituting'supports for the draft-bar.

4. In a draft-equalizer, the combination with a draft-bar, of whiftletrees connected thereto, a body-bracket, fastening devices adjustable toward and from each other upon the bracket for securing the bracket against horizontal movement and at separated points, and divergent links attached to the draft-bar and connected to the body-bracket at separated points, thereby holding the draft-bar against horizontal swinging movement.

5. In a draft-equalizer, the combination with a draft-bar, of a body-bracket having bolt-openings and a transversely-disposed slot, fastening bolts passing through the openings and the slot, and links pivotally connected to the bracket and the draft-bar.

6. In a draft-equalizer, the combination with a draft-bar, of a substantially A-shaped bracket-frame, means for securing the terminals of the frame to a plow or other clevis, a stirrup attached to the rear face of the draftbar contiguous to one end, and sets of links secured to the bracket-frame, one of said sets being connected to the stirrup.

7. In combination with the clevis, the bracket-frame adjustably mounted at one side of and along the same, the whiffletrees, the draft-bar, and loose connections between the draft-bar and the bracket-frame, said connections being arranged at an angle to each other and attached to the bracket-frame one in advance of the other.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
